Provided is an optical particle detection device capable of corresponding to the change of wavelength of light irradiated to particles. The optical particle detection device has a light source (1) for emitting detection light, a conversion unit (21) for converting the detection light into parallel light, a condensing reflector (31) for reflecting the detection light converted into parallel light towards a focus, an injection device (3) for injecting an air current including particles to the focus of the condensing reflector (31), and a light detection unit (4) for detecting scattered light or fluorescent light by irradiating particles contained in the air current. |
